Household Food Consumption and Wastage during the COVID-19 Pandemic Outbreak: A Comparison between Peru and Brazil

From the shopping basket to the landfill: Drivers of consumer food waste behaviour

The EU, where nearly 57 million tonnes of food waste are generated annually, has set a target to halve this amount by 2030. However, the amount of food waste produced varies greatly between EU countries. While several EU countries are far from reaching this target, the Czech Republic already meets it. Despite this, little to no attention is paid to Czech consumers' food waste behaviour. This study responds to the unfulfilled need by drawing attention to food waste and its reduction, and possibly even serving as a model example for the EU target. We identify key factors influencing food waste by conducting a survey with 1,551 respondents on stated preferences. The results using the PLS-SEM approach show that the price of food does not have as great an impact on the level of food waste as its characteristics or planning, which is part of consumers' purchasing behaviour. Furthermore, consumers' attitudes and awareness of food waste reduce food losses. The causes of food waste remain decidedly similar before and during the pandemic COVID-19, except that people paid more attention to food attributes during the pandemic. Product attributes are an essential part of decision-making, especially for women and people with higher levels of education. We conclude that it is desirable to sufficiently educate and teach consumers to properly plan their consumption and better estimate the amount of food needed when shopping, which should be a conscious decision rather than an impulsive one.

Why people are bad at leftover food management? A systematic literature review and a framework to analyze household leftover food waste generation behavior

Food waste is a significant global problem. In the global north, households are a major driver of food waste generation and also a key enabler of solutions to address the issue. Leftover food management is identified as one of the key areas that can be targeted to reduce food waste at home. Although a large body of literature exists on household food waste and its drivers, managing food leftovers has received less attention. This state-of-the-art review focuses on leftover food management practices with the view of supporting practitioners in designing and prioritizing behavioral interventions to reduce leftover food waste in households. It uses the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) framework to select articles for the review. Based on 42 primary studies, this systematic review identifies a range of psycho-social, socio-demographic and lifestyle factors influencing leftover food waste generation behavior at home. Moreover, household food handling skills and knowledge, and availability and accessibility to infrastructure facilities affect leftover food waste generation behavior. Based on the synthesized literature, Leftover Food Waste Generation Behavior (LFWGB) Framework has been developed. The framework conceptualizes psycho-social, personal and lifestyle factors driving leftover food management behaviors at home. Reducing food leftovers must be given top priority along with consumer meal planning and food preparation skills in household food waste reduction interventions and campaigns.

A review of the effects of COVID-19 on food waste

The COVID-19 pandemic exposed significant vulnerabilities in systems of production and consumption. In particular, the economic and social implications of the pandemic highlighted the urgent need for more sustainable and less impactful practices of food production and consumption. Through a systematic literature review, this paper seeks to assess how the pandemic affected the phenomenon of food waste, with the aim of assessing whether the pandemic stimulated changes amongst food system actors, especially consumers. The findings indicate that consumers generally reported behavioural changes during the pandemic and claimed to have adopted sustainable practices that could contribute to reducing food waste. The results also reflect the rapid diffusion of practices such as food delivery during the pandemic, which requires further investigation in terms of its effects on the environment. Simultaneously, supply-demand shocks and disruptions were reported in the areas of production, processing, and retailing, suggesting the occurence of ripple effects. A call is made for greater resilience in the food system, through the adoption of sustainable and less impactful practices, supported by policy.

The vulnerability of a centralized food system: An opportunity to improve food security in times of COVID-19-Peru perspective

COVID-19 has had a strong impact on the food supply chain (FSC) in many countries. The objective of this study was to determine the vulnerability of the FSC in a developing country, namely Peru. The main weakness of the FSC is its centralization, and COVID-19 aggravated this deficit in Peru. This prevents its stability on a large scale, especially in rural areas, which suffer from food and nutritional insecurity. In spite of this, the food system was stabilized due to agricultural, livestock and fishing potential of Peru. In addition, the efforts of local producers and informal vendors helped to maintain the availability of food throughout the country. Several examples of short (and decentralized) FSC were described, highlighting their importance for supplying the population in different areas of the country. In addition, they allow for rapid resolution of interruptions such as the current health crisis. Also mentioned are some suggestions for strengthening Peru's FSC such as the use of new technologies, self-production of food and the exploitation of non-conventional food sources. Emphasis is placed on the importance of environmental sustainability of the FSC and of implementing strategies to prevent illness among workers. This study aims to reflect on the importance of having a resilient and flexible FSC. Taking Peru as a model, the information provided is useful to understand how to improve the food system through the intervention of all the agents involved, such as government, academia, industry and the population.

Food supply chain waste reduction for a circular economy in the COVID-19 pandemic: a longitudinal study of New Zealand consumers

Purpose

Food waste (FW) reduction, of which household wastage comprises a large fraction, has an important role in promoting the circular economy (CE). This study investigates how certain consumer traits impact household FW, particularly in the face of external shocks.

Design/methodology/approach

The authors conducted a qualitative and longitudinal study, spanning three periods in New Zealand. A preliminary model is constructed from the outcomes of a survey with 178 participants. Then, the authors carried out 29 semi-structured interviews to refine the preliminary model and adapt it to the analysis of household waste behavior.

Findings

Different segments of consumers have distinct response patterns in successive lockdowns, and these patterns impact household FW reduction and food supply chain (FSC) management. The key findings include (1) for government, quick responses to quash unhelpful rumors help to reduce public concerns around FSC interruption; (2) for retailers, the pandemic has hastened the growth of online shopping; being able to expand the distribution channel in a short time is a critical issue; and (3) for consumers, the experience of lockdown has different impacts on different groups of consumers. This variation of experience may either enhance or exacerbate FW in households.

Originality/value

This paper complements the existing literature on the FSC and contributes to household FW and CE literature by providing a framework that integrates external impacts, consumer segmentation to reflect on waste management, and the possible applications of the proposed framework.

Impacts of the COVID-19 pandemic on household food waste behaviour: A systematic review

Food waste has adverse economic, social, and environmental impacts and increases the prevalence of food insecurity. Panic buying at the beginning of the COVID-19 outbreak raised serious concerns about a potential rise in food waste levels and higher pressure on waste management systems. This article aims to investigate the impact of COVID-19 on food waste behaviour and the extent to which it occurs using the systematic review method. A total of 38 articles were identified and reviewed following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. The findings showed that the COVID-19 pandemic led to reductions in household food waste in most countries. Several changes in shopping and cooking behaviours, food consumption, and managing inventory and leftovers have occurred due to COVID-19. Based on these insights, we predicted that some desirable food-management habits would be retained, and others would roll back in the post-COVID-19 world. The review contributes to the food waste literature by offering a comprehensive overview of behavioural changes during the COVID-19 pandemic and future research directions.

The Clean Your Plate Campaign: Resisting Table Food Waste in an Unstable World

The COVID-19 pandemic threatens global food security and has created an urgent need for food conservation. This article presents a review of clean plate campaigns around the world. It aims to fight food waste and reveal the factors that may influence food waste. The Clean Plate Club in the US developed during wartime and relied heavily on political power for compliance, whereas the Clean Plate movement in South Korea was based on religion. China’s Clean Your Plate Campaign (CYPC) has gone through two stages: CYPC I and CYPC II. The latter occurred during the unstable period of the COVID-19 pandemic. It was large-scale and more strongly enforced than CYPC I. In China, CYPC has relied more on personal virtue than on politics or religion. Culture, policy, COVID-19, and behavior are all important social factors that influence food waste. Specifically, two cultural values are drivers of food waste in China: hospitality and face-saving (mianzi). In terms of policy, China’s food waste law mainly relies on persuasion; it lacks any power of enforcement. Laws in France and Italy, by contrast, focus on re-using food and involve both coercion and incentives. COVID-19 may have led to panic purchasing and stockpiling, but, in general, it has resulted in a reduction in food waste.

Psychological Barriers to Sustainable Dietary Patterns: Findings from Meat Intake Behaviour

Sustainable diets are patterns that change consumer behaviour towards more balanced and plant-based habits. This study investigates the effect of individuals’ predisposition to adopt sustainable diets while reducing meat intake by measuring their psychological proximity to meat. Using an online consumer-based platform, a cross-sectional survey collected responses from 497 individuals. Questionnaire items included 43 questions prospected from the literature, coded as practical and essential barriers and measured on a modified 7-point Likert scale. The results showed some paradoxes, as a high predisposition to adopt a sustainable diet coexists with a high predisposition to consume animal-based proteins. The main perceived barrier to adopting a plant-based diet was the enjoyment of eating meat, followed by the lack of information about plant-based diets. Barriers related to meat alternatives remained the highest above all the others. It confirms that, for local consumers, meat remains a usual option and is easier to prepare. When investigating the moderating effect of barriers on the predisposition to behaviours towards meat intake reduction, no effect was confirmed. However, we found a U-shaped moderating effect for plant-based meal increase, confirming the psychological proximity of the meat consumption effects under the lens of the Construal Level Theory and Transtheoretical Model. These findings call for further research on the effectiveness of measuring psychological barriers related to sustainable diet adoption.
